,Q1. A drug has a high hepatic extraction ratio. Which alteration in liver blood flow
will have the most significant impact on its oral bioavailability?
A. Decreased liver blood flow increases bioavailability.
B. Decreased liver blood flow decreases bioavailability.
C. Increased liver blood flow increases bioavailability.
D. Changes in liver blood flow have minimal impact on bioavailability.
Correct Answer: A. Decreased liver blood flow increases bioavailability.
Rationale: For high-extraction drugs, hepatic clearance depends on liver blood flow.
Reduced blood flow decreases first-pass metabolism, increasing systemic bioavailability.
Conversely, increased flow enhances metabolism, reducing bioavailability.
Why Wrong:
B - This is the opposite; decreased flow reduces metabolism, not increases it, so
bioavailability rises.
C - Increased flow increases first-pass metabolism, lowering bioavailability, not
increasing it.
D - Flow changes are significant for high-extraction drugs, unlike low-extraction
drugs.

Q2. A drug is a weak acid with pKa 4.5. In a patient with severe metabolic alkalosis
(urine pH 8.0), which statement best describes its renal excretion?
A. Excretion is increased because the drug is ionized in alkaline urine.
B. Excretion is decreased because the drug is non-ionized in alkaline urine.
C. Excretion is unchanged because pKa is far from urine pH.
D. Excretion is increased because the drug is non-ionized in alkaline urine.
Correct Answer: A. Excretion is increased because the drug is ionized in alkaline
urine.
Rationale: Weak acids are more ionized in alkaline urine, reducing tubular reabsorption
and increasing excretion. Non-ionized forms are reabsorbed; alkaline urine favors
ionization of acids.
Why Wrong:
B - Alkaline urine ionizes weak acids, not keeps them non-ionized.
C - pH 8.0 is 3.5 units above pKa, significantly altering ionization.
D - Non-ionized drugs are reabsorbed, not excreted more.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 4
Q3. A drug is a competitive antagonist at receptor R. Which change in the
concentration of endogenous agonist will overcome the blockade?
A. Decrease in agonist concentration
Page 3
, B. Increase in agonist concentration
C. No change in agonist concentration
D. Increase in antagonist concentration
Correct Answer: B. Increase in agonist concentration
Rationale: Competitive antagonists bind reversibly to the same site as the agonist. Raising
agonist concentration can outcompete the antagonist, restoring the response. This is a
hallmark of competitive antagonism.
Why Wrong:
A - Decreasing agonist concentration would worsen blockade.
C - No change would not overcome the blockade.
D - Increasing antagonist concentration would enhance blockade.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 2
Q4. Which drug property is most likely to increase the risk of dose-dependent
hepatotoxicity?
A. Formation of reactive metabolites
B. High protein binding
C. Long half-life
D. Renal excretion
Correct Answer: A. Formation of reactive metabolites
Rationale: Reactive metabolites can cause cellular damage, leading to dose-dependent
hepatotoxicity. This is seen with drugs like acetaminophen. Other properties affect kinetics
but not directly cause hepatotoxicity.
Why Wrong:
B - High protein binding affects distribution, not direct hepatotoxicity.
C - Long half-life affects accumulation but not direct hepatotoxicity.
D - Renal excretion is not directly linked to hepatotoxicity.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 5
Q5. A patient is on a drug that is a CYP3A4 inducer. Which co-administered drug is
most likely to have reduced therapeutic efficacy?
A. Warfarin
B. Digoxin
C. Lisinopril
D. Metformin
Correct Answer: A. Warfarin
Rationale: Warfarin is metabolized by CYP3A4. Induction increases its metabolism,
reducing plasma levels and anticoagulant effect. Digoxin is not significantly CYP3A4;
